public class IlvJComboBox extends JComboBox
JComboBox that
contains workarounds against Swing globalization bugs.
Depending on the renderer that you install on
an instance of this class, you may have to do additional coding in order
to get the component orientation of the list items correct:
renderer, there is
nothing else to do: The IlvJComboBox ensures the correct
component orientation.renderer that does not
paint text and that is independent of the component orientation,
there is nothing else to do either.renderer with a
getListCellRendererComponent method that propagates the
component orientation from the JList argument to the
rendering component, there is nothing else to do either.renderer with a
getListCellRendererComponent method that does not
propagate the component orientation, then if that renderer is a
subclass of JLabel, you can use
setCustomJLabelBasedRendering(true) to have the
component orientation propagated to the renderer.JComboBox.AccessibleJComboBox, JComboBox.KeySelectionManagerJComponent.AccessibleJComponentContainer.AccessibleAWTContainerComponent.AccessibleAWTComponent, Component.BaselineResizeBehavior, Component.BltBufferStrategy, Component.FlipBufferStrategyactionCommand, dataModel, editor, isEditable, keySelectionManager, lightWeightPopupEnabled, maximumRowCount, renderer, selectedItemReminderlistenerList, TOOL_TIP_TEXT_KEY, ui, UNDEFINED_CONDITION, WHEN_ANCESTOR_OF_FOCUSED_COMPONENT, WHEN_FOCUSED, WHEN_IN_FOCUSED_WINDOWaccessibleContext, BOTTOM_ALIGNMENT, CENTER_ALIGNMENT, LEFT_ALIGNMENT, RIGHT_ALIGNMENT, TOP_ALIGNMENTABORT, ALLBITS, ERROR, FRAMEBITS, HEIGHT, PROPERTIES, SOMEBITS, WIDTH| Constructor and Description |

| Modifier and Type | Method and Description |
|---|---|
void |
addActionListener(ActionListener listener)
Adds an

the user selects an item in this combination box. |
protected Object |
defaultRendererAdaptedValue(Object value)
Returns the value that is rendered by the default renderer.
|
Dimension |
getPreferredSize()
Returns the preferred size of this combination box.
|
boolean |
isCustomJLabelBasedRendering()
Returns whether the component orientation workaround is used for a
custom renderer that is a subclass of
JLabel. |
void |
setComponentOrientation(ComponentOrientation o)
Sets the language-sensitive orientation that is to be used to order
the elements or text within this component.
|
void |
setCustomJLabelBasedRendering(boolean use)
Sets whether the component orientation workaround is used for a
custom renderer that is a subclass of
JLabel. |
void |
setRenderer(ListCellRenderer renderer)
Sets the renderer that paints the list items and the item selected
from the list in the JComboBox field.

JComboBox.public void setCustomJLabelBasedRendering(boolean use)
JLabel.
This is disabled by default.
The component orientation problem results in wrong alignments in
right to left orientation in certain older Swing UIs.
By default, the renderer installed by the UI is modified to solve
the component orientation problem. This however does not work
for custom renderers that are set explicitly. In this case,
the custom renderer must support right to left component
orientation. For a custom renderer that does not support it but is
a subclass of JLabel, this convenience option can be
enabled before setting the component orientation on the combo box.
In this case, the horizontal alignment of the label is modified
to be right when the component orientation is right to left.
